And he couldn't be more spot on. There is no shout for last man back, and as the post states above he could have flown in with a scissor tackle and potentially broken Stewart Downing's or his own leg, and would have most definitely got a red card.

Any Liverpool supporter would be fucking livid if Glen Johnson was put in a similar situation and decided to do nothing about it.

A bit of a different situation, though, as Valencia was in the box at the time when Glen had "recovered" enough to "make a challenge". If that challenge on Downing is in the box, its obviously a red; it's not even a challenge that would be made in the box (goes without saying).
